Recommended Environmental Practices for Electronic Equipment Design in Heavy-Duty Vehicle Applications

2019-09-17
WIP
J1455
The scope of this Recommended Practice encompasses the range of environments which influence the performance and reliability of the electronic equipment designed for heavy duty on and off road vehicles, as well as any appropriate stationary applications which also use these vehicle derived components. A few examples of such vehicles are on and off highway trucks, trailers, buses, construction equipment, and agricultural equipment including implements.

Seven Conductor Cable - Truck and Bus

2019-09-12
WIP
J1067
This SAE standard establishes the minimum construction and performance requirements for seven conductor 1/8 1/10 5/12 cable for use on trucks, trailers and converter dollies. Where appropriate, the standard refers to two types of cables, (Type F and S, described later in the standard), due to the variation in the performance demands of cables used in flexing and stationary applications.

Seven Conductor Cable for ABS Power - Truck and Bus

2019-09-12
WIP
J2394
This SAE standard establishes the minimum construction and performance requirements for seven conductor 1/8 2/10 4/12 cable for use on trucks, trailers and converter dollies. Where appropriate, the standard refers to two types of cables, (Type F and S, described later in the standard), due to the variation in the performance demands of cables used in flexing and stationary applications. While the document’s title refers to ABS Power to differentiate the document from the SAE J1067 standard that it supersedes, the scope applies to both the primary green cable for powering ABS and lighting and the yellow auxiliary cable of the same construction.

Coiled Electrical Cable - Truck and Bus

2019-09-12
WIP
J2222
This SAE Standard establishes the minimum performance and endurance requirements for coiled electrical cables used for hookup between trucks, trailers and dollies. The component standards SAE J2394 (replaced SAE J1067) for cable and SAE J560 for connectors must be consulted to determine the complete performance and endurance requirements of the system. Related TMC Recommended Practices may be consulted for information associated with selection, installation and inspection of these coiled electrical cables. This document is intended to set out requirements for the majority of conditions rather than for specialized applications or environments.

Auxiliary Two-Conductor Electrical Power Connector for Truck-Trailer High-Power Jumper Cable

2019-08-20
CURRENT
J3082_201908
This SAE Standard provides the minimum requirements for high-power, two-conductor jumper cable plug and receptacle for truck-trailer jumper cable systems. It includes the test procedures, design, and performance requirements. This document covers receptacles rated 12 VDC nominal and at more than 30 A (amperes) up to and including 150 A, and is intended for a single circuit with one power conductor and one common return conductor. Single-conductor high-current connectors are not recommended for future designs because of inadequate ground return through fifth wheel/king pin. Cable size selection is to be made by the vehicle OEM for specific applications and the specific voltage drop requirements of those applications.

Recommended Practice for Identification of Standardized Truck and Tractor Electrical Circuits

2019-01-08
CURRENT
J2191_201901
This SAE document defines a recommended practice for implementing circuit identification for electrical power and signal distribution systems of the Class 8 trucks and tractors. This document provides a description of a supplemental circuit identifier that shall be utilized in conjunction with the original equipment manufacturer’s primary circuit identification as used in wire harnesses but does not include electrical or electronic devices which have pigtails. The supplemental circuit identifier is cross-referenced to a specified subsystem of the power and signal distribution system identified in Section 5.
